PlLE-WIRE FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 512,063, dated January2, 1894. Application filed May 4, 1893. Serial No. 473.038. (N0 model.)

To all whom it may concern.-

Be it known that I, GUSTAV SEGSOHNEIDER, a cltlzen of the United States,residing in Yonkers, county of Vestchester, and State of New York, haveinvented certain new and useful Improvements in Pile-WVires for 1 00mmof which the following is a specificaion.

In Letters Patent for an improved pilewire for looms, No. 500,275, datedJune 27, 1893, I haveshown and described a pilewire for looms to one endof which is attached a sheet metal holder into which a removable cuttingblade is inserted and retained at its inner end by a spring or othersuitable means. The sheetmetal holder was applied by means of tongues tothe recessed end of the pilewire and attached thereto by brazing,soldering or otherwise. I have since found that a separate spring forretaining the inner end of the cutting blade in the holder can bedispensed with and the blades retained byimparting the requiredspring-action to the blade itself, by providing the body of the samewith an L-shaped slit, into which the outer end of the holder takes soas to lock thereby the blade firmly in position.

For this purpose this invention consists, first, of a pilewire for loomsin which a sheet metal holder is attached to the end of the pilewire,said holder being provided at one side of its outer end with atransversepro- ;ection that engages the cutting-blade which 1s provided with aslit that extends from the base of the blade into the body of the same.

The invention consists secondly, of a novel construction of the head ofthe pilewire in which the shank of the head is provided with alongitudinal recess and a projection in said recess into which theopposite end of the pilewire 1s inserted and retained by sheet metalcaps that extend over the end or the pile wire and that are riveted andsoldered into the corresponding depressions 01": the heads, as will befully described hereinafter and finally pointed out in the claims. 7

t In the accompanying drawings, Figures -1 and 1 represent aside-elevation of my improved pilewire for looms showing respect- 1velythe holder in which the blade is retained and the opposite end to whichthe head of the pilewire is attached. Figs. 2 and 2 represent top-viewsof Figs. 1 and 1;

Figs. 3 and 3 vertical transverse sections respectively on lines 3, 3and 3, 3, Figs. 1 and 1. Fig. 4,1's a horizontal section of the holderand cutting blade, on line 4 4 Fig. 1. Fig. 5, is a top-view of theholder and blade, showing the latter in the act of being inserted 'intothe holder. Fig. 6, is a side-elevation of the cutting-blade, shown asdetached from the holder. Figs. 7, 8 and 9, represent respectively aside-elevation, a top-view and a horizontal section on line 9, 9, Fig.7, of a modified construction of the holder and cutting-blade in whichthe curved lug or guard at the outermost end of the holder is dispensedwith. Figs. 10, 11 and 12, represent a side-elevation, a top-view and ahorizontal section on line 12, 12 Fig. 10, of another modificationofithe holder and cutting blade, and Fig. 13, is a vertical transversesection on line 13, 13, Fig. 10.

Similar letters of reference indicate corre-' sponding parts.

Referring to the drawings, A represents a pilewire for looms and B ablade-supporting holder which is made of suitable sheet metal,preferably of sheet steel. The holder B is made from a blank, the widthof which is equal to twice the height of the pilewire plus the width ofthe base of the same, so that when the blank is bent up into shape itforms a pocket-like receiver for the cutting bladeO. The end of thepilewire is inserted into the inner end of the holder and rigidly unitedtherewith by means of brazing, soldering or otherwise. The outer end ofthe holder B is provided with a lug b which is bent at a suitable angleof inclination to the vertical center-plane of the pilewire so as toform aguard for the holder B and prevent it from striking the reeds. Theslight curve or inclination.

imparted to the guard 19 produces the-ready glancing 01f of the end ofthe holder from the reeds in case it should abut against the same so astosecure thereby the reliable movement of the pilewire during theingoing motion of the same. The outer end of the holder B next to theguard lug b is provided with a recess b and at the opposite side with aproedge remain blunt.

jection b which engages the recess b when the blank is bent into shapeso as to form the holder B. The blade Cis made of triangular shape ornearly so, the inner tapering edge of which is sharpened while the baseand outer The body of the blade 0 is provided with an L-shaped or otherslit d which extends from the base into the body, as shown in Fig. 6,the lateral end of the slit being somewhat larger than the vertical partand slightly inclined at its lower edge for the purpose of facilitatingthe interlocking of the projection b with the slightly enlarged end ofthe slit d and lock thereby the cutting-blade C rigidly to the holder 13when the former is placed into position therein.

For connecting the blade to the holder, the

' outermost end of the blade on the left of the slit d is bent sidewiseas shown in Fig. 5, so as to bear on the outside of the holder B Whilethe remaining portion of the blade is inserted into the holder and movedalong the same until its projection 19' enters into the larger portionof the slit B, which is indicated by a slight click that is producedwhen the projection 17' springs into the slit d. slitted body of theblade 0 abuts against each end of the shoulder formed by the transverseprojection b of the holder, while the outer end of the blade restsagainst the curved guard 12, as shown clearly in Fig. 1. In this mannerthe blade is firmly locked into the holder by. the spring-action of theslitted body of the blade without requiring a special spring-tongue forretaining the inner tapering end of the blade as in my priorpatentreferred to. The opposite end of the pilewire A is attached to thehead E the shank E of which is proved with a longitudinal recess e thatextends nearly up tovthe eye E The end of the pilewire A is insertedinto the recess e of the shank E. A lug or projection e at one side ofthe recessed shank E engages a corresponding recess 6 in the end of thepilewire A. The shank-E has depressions at both sides and at each sideof the pilewire, so as to permit the insertion of sheet metal caps f f,of disk or other shape, which are attached by rivets f f to the shank E,one rivet being arranged at each side of the end of the pilewire. Afterthe rivet-connection of the caps with the shank of the head E is made,the entire head is dipped into solder which fills up all the intersticesbetween the shank and caps and the depressions above thecaps so that thelatter are flush with the sides of the shanks as shown in Fig. 3 Theriveted and soldered caps produce the rigid connection of the shank ofthe head E with the end of the pilewire in lateral direction, while theprojection at the inner edge of the recess of the shank E and theinterlocking,

recess inthe end of the pilewire secure the rigid connection of thepilewire with its head against the longitudinal strain exerted on theThe parts during the cutting motion of the'pile- Wire. 7

In Figs. 7 to 9 a modified form of the con-' nection of the cuttingblade withthe holder B is shown, in which the curved lug or guard b atthe outer end of the holder Bis dispensed with and made integral withthe outer end of the blade by which the same effect 1s obtained. In thiscase the slit d is extended into the curved end of the blade, so as torender the same more yielding. and elastic, the interlocking of theholder and the blade being otherwise substantially the same as thatshown in Figs. 1 to 5. Another connection of the holder and blade isshown in Flgs. 10 to 13, in which the holder B is extended at that sideback of the blade, the extension 11 being adapted to engage anopeningunthe body of the blade, whereby an additional interlockingbetween the holder and blade as obtained.

The advantages of my improved'pilewlres for looms are, first, that theblade can be readily removed or inserted by the fingers withoutrequiringa pair of pliers or other tool'for this purpose; secondly, thatthe-connection between the holder and the blade 15 made withoutrequiringa separate locking spring, which when the pilewire is 1n usefor some time, is liable to wear out and become loose; thirdly, that theheadis attached-to the opposite end of the pilewire 1n asrmple and veryeffective manner that permltsthe quick and ready connection of'the partsand produces the reliab1e connection of the same, both as againstlongitudinal and lateral strain or displacement.

Having thus described my invention, I claim as new and desire tosecureby Letters Patent- I 1.
